It is equipped with mechanisms such as the countercurrent multiplication system, which allows efficient water reabsorption, and the formation of an osmotic gradient by sodium ions from the cortex ...

Thus they absorb water on the one hand and solute on the other. This is called the countercurrent multiplier system, which is responsible for maintaining an osmotic medullary gradient in the outer ...

IT is well established that hypertonic urine is produced in. the kidney by means of a countercurrent multiplier system and that the formation of such urine requires a hyper-osmotic medullary ...
